you should add balance to the game so you can have money maybe add a shop instead of just using grass to buy something you could use in-game money
We have that in /economy, and we have been using grass as currency since 2012 in the original skyblock server & classic.
But using grass is what makes this server unique. Go to /economy, you'd most likely prefer that server if you don't like using grass as currency.
Most likely the reason /skyblock has the majority of its players is due to the grass/ rarer item currency. That is one of the reasons I really like this skyblock, and why I initially chose to play. For economy based skyblock servers there’s a lot more choice out there, so players have more options to explore and find one that suits them. If the currency were to be changed a lot would have to be changed with it: tradeshops, lottery, voting etc. Not to mention a wave of very angry players. Absolutely no support, it is fundamental to skyblock that it retains its unique currency and economy.
